Aircraft cargo hold mounting device

Abstract

A mounting device for mounting functional devices within a cargo hold of an aircraft. The mounting device includes at least one surface unit and a plurality of functional devices which can be mounted on the surface unit in such a way that the surface unit can be inserted together with functional devices mounted thereon into the aircraft cargo hold in the manner of a template in such a way that all the functional devices come to lie in defined mounting locations in the cargo hold and can be mounted on supporting structures of the aircraft or the cargo hold without adjustment in relation to the surface unit.

The invention claimed is: 
     
       1. A mounting device for a cargo hold of an aircraft, the mounting device comprising at least one surface unit, and a plurality of functional devices are mountable on the surface unit in such a way that the surface unit, together with the functional devices mounted thereon, are insertable into the cargo hold in such a way that all functional devices come to lie in the cargo hold at defined mounting positions and are mountable without adjustment relative to the surface unit on support structures of the aircraft or of the cargo hold respectively, wherein the surface unit comprises a sandwich structure comprising:
 a. a first core layer of fibre-reinforced plastic; 
 b. a second core layer of fibre-reinforced plastic; 
 c. at least an intermediate layer, which is embedded between the first and second core layer, 
 and wherein the thickness of the intermediate layer decreases in a transition region towards an edge region. 
 
     
     
       2. The mounting device according to  claim 1 , wherein the functional devices are designed such that they are fastenable to the surface unit by screw devices. 
     
     
       3. The mounting device according to  claim 2 , wherein the screw device is actuatable on a side of the surface unit which is opposite the functional device. 
     
     
       4. The mounting device according to  claim 1 , wherein the surface unit is designed for the formation of a gas-tight and/or watertight barrier between its upper side and its underside. 
     
     
       5. The mounting device according to  claim 1 , wherein the surface unit comprises sealing lips which are arranged at edges of the surface unit. 
     
     
       6. The mounting device according to  claim 1 , wherein the surface unit is designed to form an accessible floor. 
     
     
       7. The mounting device according to  claim 1 , wherein the surface unit comprises a fibre-reinforced plastic material. 
     
     
       8. The mounting device according to  claim 1 , wherein reinforcing struts are embedded in the sandwich structure. 
     
     
       9. The mounting device according to  claim 1 , wherein the surface unit has reinforcing means in sections on which the functional devices are mountable. 
     
     
       10. The mounting device according to  claim 1 , wherein the surface units are designed for mounting in the base region. 
     
     
       11. The mounting device according  claim 1 , wherein the surface units are designed for mounting in the side and ceiling region. 
     
     
       12. The mounting device according to  claim 1 , wherein the surface units comprise defined kink sections in which rigidly designed planar sections are mountable at an angle to one another in the aircraft. 
     
     
       13. A method for mounting functional devices within a cargo hold of an aircraft, comprising the steps of:
 a) pre-mounting functional devices at predefined locations on a surface unit outside the aircraft, the surface unit being at least partly made of fibre-reinforced plastic, the functional devices comprising at least one roller track; 
 b) inserting the surface unit together with the pre-mounted functional devices into the cargo hold of the aircraft in a final position in such a way that the functional devices come to lie in the cargo hold at defined mounting positions and are mountable without adjustment relative to the surface unit on support structures of the aircraft; 
 c) fastening the functional devices together with the surface unit to supporting structures of the aircraft, wherein the at least one roller track is attached to a plurality of transverse beams of the aircraft. 
 
     
     
       14. A cargo hold of an aircraft comprising support structures, a mounting device, the mounting device comprising at least one surface unit, and a selection of functional devices, the selection of functional devices comprising at least one roller track, wherein the selection of functional devices are pre-mounted on the surface unit in such a way that the surface unit, together with the pre-mounted selection of functional devices are insertable into the cargo hold and attachable to the cargo hold in a final position in such a way that the selection of functional devices come to lie in the cargo hold at defined mounting positions and are mountable without adjustment relative to the surface unit on support structures of the aircraft or of the cargo hold respectively, wherein the roller track is pre-mounted to the surface unit such that the roller track extends in a longitudinal direction of the aircraft and is attachable to a plurality of transverse beams being part of the support structures, wherein the surface unit is at least partly made of fibre-reinforced plastic. 
     
     
       15. The cargo hold of an aircraft according to  claim 14 , wherein the functional devices are designed such that they are fastenable to the surface unit by screw devices. 
     
     
       16. The cargo hold of an aircraft according to  claim 15 , wherein the screw device is actuatable on a side of the surface unit which is opposite the functional device. 
     
     
       17. The cargo hold of an aircraft according to  claim 14 , wherein the surface unit is designed for the formation of a gas-tight and/or watertight barrier between its upper side and its underside. 
     
     
       18. The cargo hold of an aircraft according to  claim 14 , wherein the surface unit comprises sealing lips which are arranged at edges of the surface unit.
